HENRY P. ROBERTS, OF BOSTON, MASSACHUSETTS,

` HAIR-DRIER.

Specification of Letters Patent.

Patented Aw. 7, i917.

Application filed August 18, 1915. Serial No. 46,177.

ing or the like. l/Vhile a number of devices have been produced for this purpose, so farz as known to me they have been relatively expensive to produce and inconvenient to operate. The device embodying my invention is of simple construction so that it may be manufactured very cheaply and is so arranged that the heat required while the device is in use may be readily obtained at a negligible cost.

My invention lwill be fully understood from the following description when taken in connection with the accompanying drawings and the novel features thereof will be pointed out and clearly defined in the claims at the close of the specification.

In the drawings, Figure 1 is a side elevation partly in section of a device embodying my invention.

Fig. 2 is a sectional detail enlarged of one of the teeth shown in Fig. 1 secured to a portion of the heater member.

Fig. 3 is a view similar to Fig. 2 showing a modified form of tooth embodying my invention.

Having reference to the drawings there is shown in Fig. 1 a hair drying device provided with a hollow cylindrical member 11 which may be of any suitable heat transmitting material such as tin, aluminum or the like. One end of the cylinder 11 is i closed as shown at 12, the other end having a neck 13, a portion of which is provided with spiral corrugations 14 to receive a correspondingly corrugated cap 15 having a suitable washer of cork or the like 16 and l adapted to make a tight non-leaking fit with the said neck. The cylinder 11 is provided at one end with a handle 17 of non-heat transmitting material such as wood or the like which may be secured to the cylinder in any suitable way, but in the device shown is secured by means-of a U-shaped metallic strip 18. The metallic strip 1S is soldered to the cylinder 11 and is formed with legs 19 which are adapted to fit tightly within recesses 201 formed in the handle 17 in which they may be secured in any well known manner preferably by adhesive. In the. handle 17 is an elongated opening 20 which 1s so arranged that the heater may be conveniently held to comb and dry the hair without danger of burning the fingers.

lThe cylinder 11 provided, preferably on the side opposite to that at which the handle 17 is secured, with an elongated slot or opening 21 shown in Fig. 2. Over the slot 21 a series of hollow teeth 22 are secured by means of a curved back 23 integral with the teeth and adapted to iit over the cylinder 11. rllhe teeth and back are preferably of metal but may be of any other well known heat transmitting material. The back 23 is arranged to entirely cover up the opening 21 and being adapted to lit over a portion of the cylinder 11 may be readily secured to it so that a water tight joint is obtained in any well known manner as by riveting, soldering or the like. By this construction the hollow interior 211 of each tooth is connected with the interior of the cylinder 11. V\7hile Il have described in detail the construction preferred, 1 do not wish to limit myself to this form for it is obvious that the teeth may be secured to the cylinder in any well known manner.

The hollow cylindrical heating member is adapted to be filled with hot water which may be readily accomplished by removing the cap 16 and holding the heater under a. faucet or the like. The cap is then replaced and the device is immediately ready for use for the hot water instantly heats up the cylindrical heating member 11 and the teeth 22. In practice the device is used as a comb, the hot teeth operating to open up and separate the strands of wet hair and to bring them in contact with the heating mem ber with the result that the hair is dried in a relatively short time. In most cases one filling of water will completely dry the hair, but if it is found that more heat is required, the device may be readily re-filled.

In Fig. 3 is shown a solid tooth 25 which may be used instead of a hollow tooth if desired. When this form of tooth is employed it is not necessary to provide an opening 21 in the cylinder 11 the back 26 being secured to the cylinder and the metal in the tooth `and cylinder acting 'asf-a'L conductor for the heat.

I regard my inventionzas'importantiior the device embodying it is simple, eflicient and both inexpensive to produce and to opcrate and is so arranged that the heating medium. requiredfmay be readily] obtained. It is not attended with the. inconvenienceV of a cord attachment necessary'for the ordinary electrical heating device and isk furthermore free from =-all danger of injuring ytheevhair which is apt to be the casewhere toofhigh a degree of heat is employed for? the vboiling point of water is not suiiciently hot to inofl teeth and a width less than that of said 'plateyandmeans for securing said plate and cylinder together in a position to enable each of said hollow teeth to Communicate Y'with the interior of saidqcylinder through thesaid elongated opening.

2. In. adeviceofthe character described, a hollow cylindrical member, a series oi' teeth secured at one side of said cylinder, a U-shaped memberfsecured to said cylinder atthe other side thereof with its legs projecting outwardlytherefrom, and a hand Opening formed therein and having holes at two sideslthereof within which the legs of said U-shapedmember are received. Y .Inltestimony whereof I aiX my signature, in presence of two witnesses.
